For a color exercise, I did a couple of sketches using pico 8's full 32 color palette. It's not always easy to figure out when to use dithering and when to choose another color. Anyway, if nothing else, this might inspire some folks for their in game graphics. A sun set in a southwester US kinda thing and a more 'rocky mountain' scene during the day.

Neither of these are finished, they're just sketches, mostly working with color combinations.

These look great! I really love the use of the PICO-8 color palette as a creative constraint.
